Get in the spirit of summer by wearing a wreath of flowers in your hair and take a spin around the midsommarpole at the American Swedish Historical Museum’s annual Midsommarfest in late June. Midsommarfest is a day of fun for the entire family with food, music, dance, raffles, games and activities for kids of all ages. Midsommar is one of Sweden’s most important holidays, a unique Swedish celebration, and a day to rejoice in the coming of summer at a time when daylight is at its longest.
